Literature published between 2000 to 2004 concerning electromagnetic fields (EMF) of mobile communication and electromagnetic hypersensitivity
(EHS) or unspecific symptoms of ill health, respectively, is reviewed. Basically, literature from established databases was systematically searched for.
For each study, the design and quality were evaluated by means of a criteria list in order to judge evidence for causality of exposures on effects.
Finally, 13 studies of sufficient quality were considered for this review.

In only one provocation study, individuals with self-reported electromagnetic
hypersensitivity were exposed to EMF. Their perception of field status was no better than would have been expected by chance. Results of five
randomised cross-over studies on impaired well-being due to mobile phone exposure were contradictory.

Even though these studies would allow
more reliable exposure assessment, they are limited due to short exposure period and the small study size. No firm conclusion could be drawn from a
few observational epidemiological studies finding a positive association between exposure and unspecific symptoms of ill health due to
methodological limitations. Causality of exposure and effect was not derivable from these cross-sectional studies as field status and health complaints
were assessed at the same time. In addition, exposure assessment has not been validated.

In conclusion, based on the limited studies available, there is
no valid evidence for an association between impaired well-being and exposure to mobile phone radiation presently. However, the limited quantity and
quality of research in this area do not allow to exclude long-term health effects definitely.
